My opinion on the pulse desulfators is that the marketers had a well lubed orgy with the applications engineers and the lawyers with their butt plugs already set deep said go for it and the accountants could only say if it helps the bottom line and the lawyers say were are safe making outrageous claims of magical battery restoration, then a thumbs up from us, when do we get our bonus?
My friend has a battery minder 12248, and I put it on a battery whose capacity had noticeably dropped, for 10 days it sat there happily flashing away indicating it was defying physics with that human soothing flashing green light.
No difference the next discharge. Voltage under load dropped to the same levels as before the 10 days of the magical pulse desulfation. No change at all.
Give a lesser AGM a 29.9% charge rate from 50% a few times and then hold absorption voltage until amps taper to 0.5% of capacity.
For a higher quality AGM, 40% charge rate from 50% charged until 14.4+ volts and then hold until amps taper to 0.5% of capacity.
If that does nothing, then bust out lifelines conditioning procedure and monitor the battery closely for temperature.
